  • Figure 4 is an enlarged fragmentary sectional view taken approximately along line 4-4 of Figure 3; and Figure 5 is an enlarged fragmentary view of the cover assembly of Figure 1 being used to attach a photograph to a special greeting card used in combination with the cover assembly.
  • the cover assembly 10 is adapted for use with a photograph 11 (figures 3, 4 and 5) of a single size or in a predetermined typically small range of sizes, and comprises a flexible conformable transparent polymeric sheet 12 having a thickness of up to about 0.2 millimeter (0.008 inch) such as polyester in the range of 0.0127 to 0.051 millimeter thick and preferably 0.02 millimeter or 0.00075 inch thick, opposite front and rear major surfaces 14 and 15, a peripheral edge 16 between the major surfaces 14 and 15 having length and width dimensions exceeding the length and width dimensions of the photograph 11 by at least about 6 millimeters (0.25 inch) or in the range of about 6 to 12 millimeters, a generally centrally located rectangular viewing portion 18 that is visually transparent between the surfaces 14 and 15, and a frame portion 19 around the viewing portion 18, the viewing portion 18 having a size and shape adapted to afford viewing of a central portion of the photograph 11 with edge portions of the photograph 11 around the central portion extending along the frame portion 19; and a layer 20 of adhesive along the frame portion 19
  • the cover assembly 10 includes a layer 23 of opaque ink printed on the front surface 14 of the sheet 12 which provides means for causing at least a major part of the frame portion 19 of the sheet 12 to be opaque.
  • the layer 23 of ink could be formed by one color or many colors to provide, for example, a decorative design or represent scenery, objects or persons, etc. , or provide printed legends on a contrasting background, and the layer 23 of ink could extend onto minor parts of the viewing portion 18 of the sheet to help provide a decorative motif for the cover assembly.
  • the adhesive in the layer of adhesive 20 can be a mixture of a permanent isooctyl acrylate/acrylic acid copolymer pressure sensitive adhesive described in U.S. Patent Re. 24,906 and a repositionable pressure sensitive adhesive comprising inherently tacky elastomeric acrylate microspheres which are solid in nature and are prepared by aqueous suspension polymerization of alkyl acrylate monomers and ionic comonomers, which repositionable adhesive is described in U.S. Patent No. 3,691,140.
  • the mixture of those adhesives should comprise from 5 to 20 percent and preferably 15 percent of the permanent pressure sensitive adhesive and from 95 to 80 percent and preferably 85 percent of the repositionable pressure sensitive adhesive.
  • adhesive mixture is applied to the rear surface 15 of the sheet 12 in a layer weighing in the range of 8.37 to 16.8 grams and preferably 12.6 grams per square meter after the rear surface 15 is primed by a suitable primer, such as the vinyl chloride polymer and zinc oxide primer commercially designated VAGH that is available from Union Carbide Corporation, Danbury, Connecticut.

Abstract

Ensemble couvre-photographie se composant d'une feuille d'un polymère conformable plus grand que la photographie, avec une partie centrale transparente et une partie extérieure d'encadrement. La partie centrale présente des dimensions et une forme de nature à permettre de voir la partie centrale de la photographie, les rebords de celle-ci s'étendant le long de la partie formant l'encadrement. Ce couvre-photographie comporte une couche d'adhésif sur sa face arrière, le long de la partie encadrement, de sorte que la feuille polymère adhère fermement et se conforme aux contours du rebord de la photographie, de manière à maintenir celle-ci. La feuille polymère adhère au pourtour de la photographie de manière à ce que celle-ci soit maintenue tout en pouvant être retirée de la surface sans subir d'endommagement.
